Yep at least I understood it that way. I have watched a yt video where it was explained in pretty simple way. Now we know that you will need a dupe of a unit which has to be converted to new awakening material called frags and pearl. From 5* or 6* you can have 25 frags and 1 common pearl, 7* gives double the amount of materials. To enable brave shift on 7* neo vision, you need 75 frags and 3 common pearls

25 frags (or fragments, each unit has unique fragments, they are not shared between other units) and 1 normal pearl to awaken 7* to 7* Nv and another 50 frags and 2 normal pearls to awaken to 7* Nv with brave shift.

hmm i am not F2P but it seems the best to go this route at least until NV hits global. But i know GUMI they will bait me out with limited units. On the other hand, limited Units won´t get their NV immediately and when they get it, they will probably have another banner.

you mean edward? Did the full 25k lap and got alphonse but used the card for edward because i like damage. I was ready to use the omniprism for him but snacked a copy of edward by using the FMA tickets. xD

Or you can use someone who can entrust or do something with lb gauge... Oh wait, that uses MP.

Mp drain bosses would be folka forte as she can heal party mp as long as she has enough LB gauge.
For lower tier and if you desperate enough, I think Rem can do that one to, need half of LB gauge though
